Abstract: A method of controlling parallel operation of tapped transformers in master-follower relationship is able to control transformers with unequal voltage taps. The data of all possible voltage taps of each transformer is deposited as a characteristic value and as voltage range in coding units (A1) and one of the transformers is assigned a master function through individual connection to an automatic regulating system (C1). The characteristic value of the instantaneous tap setting of the master transformer is fed to a data bus (B) which is connected by means of a respective switch (S2) with a comparison unit (A2) of each follower transformer. It is ascertained in the comparison unit of each follower transformer whether the characteristic value of the voltage tap of the master transformer agrees, in terms of voltage range, with the voltage tap present at the follower transformer. If this is not the case, the motor drive (MA) of the <IMAGE>

Abstract: Washing fluid is fed into the scrubber in a pipe which leads to a fine distribution device inside the scrubber, and from which the fluid is sprayed in the form of fine dropletse. These droplets come into contact with flue gases which it cleans. - Fluid is fed from the scrubber via a pipe which leads to a heat exchanger, from which a further pipe recirculates it. 1-2% of the recirculating fluid is fed as waste into a tank forming part of an evapn. unit. The flow in the pipe from the scrubber can be 200 m3/hr., whilst that in the pipe to the evapn. unit can be 2-4 m3/hr. A level regulator maintains a constant washing fluid level in the scrubber, and, when required, causes more fluid to be fed into the system. - The contaminated flue gases contain e.g. hydrogen chloride and sulphur dioxide, which are absorbed by the washing process. The waste fluid in the pipe leading the evapn. unit contains, if the washing fluid is water, hydrogen chloride and hydrogen trisulphate, Where the washing fluid is water plus alkali, such as Ca(OH)2 and/or NaOH, the waste fluid contains salts, such as CaCl2, CaSO3 and CaSO4 and/or NaCl, NasSO3 and Na2SO4.

Abstract: A radial lip seal for sealing about a pin of a hinge joint is disclosed. Such seal includes an outer mounting ring, a rubber flex ring mounted inside the mounting ring, a tension ring mounted inside the flex ring, and an inner elastomeric seal ring mounted inside the tension ring. The seal ring has an inside diameter that is a sufficient amount smaller than the pin to cause the tension ring to be stretched by a predetermined amount when the seal is mounted about the pin. The tension ring is capable of exerting a radial force of at least 20 N/cm of circumference on the seal ring upon being stretched the predetermined amount. The unique construction of such a seal is effective in sealing out highly abrasive materials found in very severe operating applications, such as on earthmoving vehicles, and provides a seal having an extremely long service life in such applications.

Abstract: A method and a device for determining the angular velocity of a rotating, electrically conductive cylindrical shaft (1). A homogeneous magnetic field (3) is directed perpendicularly to the shaft in such a way that the magnetic field lines extend in the cross section plane of the shaft, perpendicular to the symmetry line (8) of the shaft. When the shaft is rotating, axial eddy currents are induced in the shaft which outside the shaft also generate a magnetic field of dipole type with a component (6) in the cross section plane of the shaft and perpendicular to the originally applied magnetic field. The magnitude of this component is determined by the angular velocity of the rotating shaft, and a measure of the angular velocity of the shaft is obtained by detecting this component with the aid of a measuring winding (7) in a plane parallel to the homogeneous magnetic field and which passes through the symmetry line of the shaft.

Abstract: A method for handling a database containing objects extending into a coordinate system, representing a multidimensional reality. The coordinate system is divisible into a plurality of defined, multidimensional intervals. Each time an object is entered into the database, the method determines the multidimensional intervals into which the object extends. For each of these intervals, the method determines the number of objects extending into the interval and compares the number of objects with a predetermined threshold value. If the threshold value is exceeded, the interval is divided into at least two smaller intervals, in order to limit the number of objects within any interval. Each interval is linked to a set of objects extending into that interval, and each object is linked to a set of intervals into which the object at least partly extends.
